CVE-2023-24993 in Tecnomatix Plant Simulation
Summary
by MITRE • 02/14/2023
A vulnerability has been identified in Tecnomatix Plant Simulation (All versions < V2201.0006). The affected application contains an out of bounds write past the end of an allocated buffer while parsing a specially crafted SPP file. This could allow an attacker to execute code in the context of the current process. (ZDI-CAN-19815)

The vulnerability CVE-2023-24993 affects Tecnomatix Plant Simulation software versions prior to V2201.0006, representing a critical security flaw that could enable remote code execution. This issue stems from improper input validation within the application's file parsing mechanism, specifically when processing specially crafted SPP files. The vulnerability resides in the application's handling of user-supplied data during the parsing process, creating an exploitable condition that could be leveraged by malicious actors to gain unauthorized system access.
The technical flaw manifests as an out-of-bounds write condition that occurs when the application attempts to parse malformed SPP files. This buffer overflow vulnerability allows an attacker to write data beyond the allocated memory boundaries of the application's internal buffer structure. The vulnerability is classified under CWE-121 as a stack-based buffer overflow, which represents a well-established category of memory safety issues commonly exploited in software security attacks. The flaw specifically occurs during the file parsing routine where the application fails to properly validate the size and structure of incoming data before attempting to store it in memory.
The operational impact of this vulnerability is severe as it provides attackers with the capability to execute arbitrary code within the context of the currently running process. This means that successful exploitation could allow an attacker to gain full control over the affected system running Tecnomatix Plant Simulation. The vulnerability is particularly concerning because it could be exploited remotely through the manipulation of SPP files, which are commonly used in industrial simulation environments. Attackers could potentially deliver malicious SPP files via email attachments, web downloads, or other attack vectors, making this a significant threat to industrial control systems and manufacturing environments.
Mitigation strategies should focus on immediate software updates to the latest available version of Tecnomatix Plant Simulation, specifically V2201.0006 or later, which contains patches addressing this vulnerability. Organizations should also implement strict file validation policies and restrict the execution of untrusted SPP files within their environments. Network segmentation and access controls should be enforced to limit potential attack surfaces, while security monitoring should be enhanced to detect suspicious file handling activities. From a defensive perspective, this vulnerability aligns with tactics described in the MITRE ATT&CK framework under the T1059.007 technique for command and scripting interpreter, as successful exploitation would likely involve code execution that could be used to establish persistence or escalate privileges within the compromised system.
